Improvement in planing-machine



Massese-w- Gef HENRY D. STOVER, OF NEW YORK, N. Y.

Letters Patent No. 84,847, dated December 8, 1868.

The Schedule referred to in these Letters Patent and making part of thesame.

Knvow all men by these presents:

That I, HENRY D. STOVER, of the city, county, and State of New York,have invented certain new and useful Improvements in Planing-Machines;and I do hereby declare the following to be a sufficiently clear andexact description of the same, so that any one skilled in such mattersmay construct and use them.

Figure 1sheet l, is. a side elevation of the machine.

Figure 2, sheet 2, is a plan, as seen in looking down upon it.'

Like letters refer to like parts in all the drawings.

The chief feature of my invention consists in a practical combinationofthe two well-known planing-devices, as thehun of Daniels planer, withthe cylinder of Woodworths, in one and the same machine, so that theymay be used either separately or in conjunction, as desired.

A. A is the foundation-frame of the machine, upon which the carriage B,for holding the lumber, travels.

C O is the 'ame for supporting the cylinder or cutter-head1), which isconstructed and arranged in the usual style of such mechanism.

At E, or just in front of the cylinder-trame and cutters, is arrangedanother frame, so constructed as' to. conveniently carry the arm-cuttersF E.

These cutters are mounted upon arms which are supported by the shaft G,said 1shaft being conveniently arranged in bearings, so as tobe capableof any desired adjustment vertically.

lhat the belt may always run to the same point, I have constructed thepulley with a spline or key, a keyway being formed in the shaft G, sothat said shaft may slide freely up and down through the pulley, itbeing held by the ratchet fm, one end of which fits in a groove in thepulley.

Motion may be communicated by a belt from the counter-shaft at Z, but Iprefer to drive it from the counter-shaft at 0, which ispaced above themachine, and at a right angle to-the shaft G; and by a quarter belt,guided and strained by the friction-roller, as at N, a much moreexcellent result is obtained with less4 mechanism.

The lumber to be planed is held upon the carriage B by the clamps ordogs R and It. The one at R is simply tin-ined with hooks and loops ateach end, to hook over the pins which project from the side of thecarriage.

The dog or clamp at R is provided with a bindingscrew, which worksthrough a pivoted nut, as at S, upon which the clamp can oscillate, soas to iitl the ends of any lumber not precisely square.

The ends of this clamp are also'cin'ved down by the edges ofthecarriage, and turned in to a rebate, or

under a projection of the carriage, which helps to hold the clamp in itsproper Working position.

In practice, I so construct the frame E of the armplaner as that itmaybe easily and quickly detached from the frame A by simply formingguides upon the frame, as indicated by the dotted lines at E', ng. l,which receives the upright, E, between them, and then it is coniined byarsingle bolt binding it to the sides of the frame A.

The combination of the arm-planer with the cylinder, as I have arrangedthem, produces many advantages not possessed by the machine whenoperated separately; and, as example, I may mention that in dressinglarge timbers, the first cut or chip is taken by the cutters F F beforepassing to the cylinder-cutters at D; consequently all the sand and dirtare thereby removed before the work of finishing is commenced.

The labor of handling and readjusting the work is alsoan, item of greatgain by such an arrangement;

and since the same frame and carriage, with the feeding-mechanism, serveadmirably for both machines, the iirst cost is much less than whenconstructed separately.

Having thus described my invention,

What I claim, and desire to secure by Letters Patent isv l.- The frameof a planing-machine, constructed in the manner described, so that thearm-cutters F F may operate simultaneously with thel cylinder D,substantially as and for the purpose set forth;

2. Ihe oscillating clamp R', when constructed in the manner and for thepurpose described.

3. The adjustable brackets N, in combination with the frame E, forsupporting the driving-shaft O, and tigh tellers, when constructed andarranged as described.

4. The clamp R,- when provided with a single hook at each end, to takehold of pins inserted in the sides of the carriage, as described.

A, when such bed is used for the support of the vertical 'and horizontalcutters I) and F E, in the manner described and for the purpose setforth. i
